TPMS system doesn't work

I have a 2020 Venue 1.6 engine. The TPMS light stays on and the TPMS screen shows an error (Check Tire Pressure Monitoring System) so I tried all the following and nothing worked:

1- Factory reset for settings
2- Reprogramming the sensors using the OBD2 device
3- Changing all sensors to new ones and I made sure they're compatible with my version of the Venue then putting all the sensors codes correctly right after.

What happens when I reenter the codes is that the error message is replaced by "Drive to display " then after driving for like 30 minutes the same error shows again.

Someone suggested that the device that receives the sensors signals in the car needs to be reset and I don't even know where this thing is to begin with.

Any suggestion is welcomed. Thank you.

I don't have an answer for you, but I feel your pain. I have found the TPMS to be basically useless as well. Better to get out your handy dandy manual tire pressure gage and check it the old fashioned way.

By the bye - I recently acquired an AIRMOTO digital tire inflator. It's about the size of a flashlight, charges by USB, and pumps up your tire in about three minutes. I love it.

Does the car still have warranty? TPMS signal receiver is built in to the Body Control unit, it could be faulty. A tire shop should be able to use their TPMS tool and put it next to the valve stems to wake up every sensor and ensure they can communicate and that each one is activated. They might be able to check the old sensors too, maybe they are not broken, I think it's unlikely that all 4 sensors would fail at the same time. What OBD2 device are you using? Can you read the TPMS trouble codes with it? The codes could help point you to the problem.

All sensors responded and it shows that they work. Even the old ones turned out to be functioning but I changed them out of desperation. Idk what devices were used as I already visited 5 different places to fix this issue.

I suppose you could try to re-seat the connectors on the Integrate Body Control Unit. It's behind the glove box, to the right of the cabin air filter...
This info is for North America Venue, other variants should be similar.
- Replacement
[TPMS Receiver (Integrated Body Control Unit (IBU))]
1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. Remove the glove box.
(Refer to Body - "Glove Box Housing")
3. Remove the IBU (A) after loosening the bolt and nut.

4. Disconnect the IBU connector (A).

This video shows how to change the cabin air filter but it also shows how to get to the IBU (to the right of the filter).

I didn't get to do the instructions above yet but thanks for the video because I read the same instructions on the online manual but the video helped getting my head around it.
What's interesting is that 2 days ago, the 2 sensors on the left side of the cars actually worked and the screen indicated that both wheels needs to be pumped and the message went away after doing so. It went back to "Drive to Display" but many kms later the same error message came back and the tpms light turned on again.

Interesting that is worked a bit. So, either the circuits are intermittent internally or the antenna connection is not good. The TPMS signals are 433 Mhz and a slightly bad connection could keep the high frequency signal from passing to the circuitry. If the problem is not internal to the IBU, un-plugging and re-plugging the the connectors on the IBU computer might restore the antenna connection. Good luck.
